Specification of Letters Patent.
rammed Jan. e, i920.
Application filed March 1, 1918. Serial No. 219,824.
To all whom t may concern:
Be it known that ANNA J. LARsoN, a citizen of the United States, residing at Sherburn, in the county of Martin and State of Minnesota, have invented certain new and useful Improvements in Loading Devices, of which the following is a specification.
This invention relates to loading devices and it is the dominant object' of the invention to prov-ide an improved loader especia ly designed for removing matter from a pile or stack and conveying the same into the body of a vehicle or other conveyance for removal.
It is also an object of the invention to provide the device with novel loading means capable of moving over the pile or stack of matter and evenly removing a portion of the saine for loading the vehicle without disturbing the pile or causing 'the collapsing or scattering of the same.
The invention also aims-to provide the loading of the device with means for automatically raising and lowering the same with relation to the pile or stack of matt er and to limit the upward and downward movement of said loading means.
-Yet another object of the invention is to provide means for moving the device after a portion of the matter of the pile has been,
removed, in order that the loading means can be again engaged therewith for further loading operations.
@ther objects will be in part obvious and iii part pointed out hereinafter.
in order that the invention and the manner of its application may be readily understood by those skilled in the art, l have in the accompanying illustrative drawings, and in the detailed following description based thereon, set forth a preferred embodiment of the invention.
In these drawings:
Figure 1 is a side elevation of the improved loader having parts broken away and shown in section,
Fig. 2 is a top plan thereof,
Fig. 3 is a vertical transverse section therethrough, and
Fig. 4 is a fragmentary transverse section.
Fig. 5 represents sectional details of the upper and lower portions of one of the threaded adjusting shafts illustrating the construction.
Having more particular reference to the drawings, in connection with which like ref- -front aXle and the uprights 4 having vertically disposed ways or slots 4 formed therei in for a purpose which will-be hereinafter described.
Suitable draft connections 5 are arranged upon the lforward transverse piece of the frame and as will be noted, serve as means for facilitating connection of suitable draft means to the frame of the device.
Supported upon the upper portions of the forward upright 3 is a conveyer supporting bed 6 having rollers 7 rotatably supported between the opposite extremities of the same, which rollers have sprocket wheels 8 secured to the opposite end of the same and engaged with the links of sprocket chains 9 passing thereover and carrying an-endless apron or conveyer 10. The apron, as will be noted,
is provided with transversely disposed rows of curved fingers l1, which fingers serve as means for engaging and removing portions of matter from a pile or stack and carrying the same forwardly into engagement with the body of a vehicle or other suitable receptacle into which said matter is discharged or dumped. To permit the raising or lowering of the forward end of the bed 6 with relation to the uprights 3, a plurality of openings 12 are formed therein in spaced relation and as will be noted, receive the shaft 18 therethrough, which shaft isV mounted in suitable bearings on said bed and has geai' wheels 14 movably mounted thereon. To permit lateral movement of the sprocket wheels 14 on the shafts 13, for a purpose hereinafter set forth, a pair of vopenings are formed in each of said shafts and receive cotter pins or like devices 15 therethrough. Thus, when it is desired to retain. the gear wheel 14 in its innermost position the inner pin 15 is arranged to engage with the outer face of the same. However, should it be desired to arrange and maintain the gear wheel 14 in its outermost position the inner pin 15 is removed and the gear wheel 14 is then moved until the outer face of the same enlll) ' are mounted upon the inner portions of the shaft 13 adjacent the inner faces ot the up- Yrights 3 and are inv mesh with the wheels 8.
Rotatably mounted in the uprights 4; which as will be understood, are hollow `and as a consequence iorm casings, are screw threaded shafts 17, the lower ends of said shafts being formed smooth as at 18 and mounted in bearings 19 secured to the opposite ends of the rear cross piece ot the traine 1, while the upper ends ot said shafts are also formed smooth and have short screw threaded sleeves 20 rotatably mounted thereon, which sleeves as will be noted, have llanges 21 formed adjacent the upper ends of the saine. ln this connection, `it is to be noted that the lower ends of the sleeves 20 are arranged in spaced relation to the threads formed on the shafts 17. Sleeves 22, similar to the sleeves 20, are rotatably and slidably arranged on the lower portion 18 ot said shafts, and have their lower ends engaged with the upper convolutions of eX- pansible coil springs 23, these sprinO's as will be noted, having bearings on the adjacent ends or" the sleeves 22. When eX- panded, the springs 23 will serve as means `tor forcing the screw threaded sleeves upwardly until recessed edges 24- of the same engage with lugsl on the lower ends of the screw threaded portions of said shafts 17. It is to be also understood, that the upper ends ot the shatts 17 will be engaged in suitable bearings arranged in the tops of the hollow casings Vthereby preventing undue lateral. movement of the saine. Gear wheels 26 are mounted upon a suitable shaft 13 journaled in bearings in proximity to the rear end of the bed 6, and mesh with acent gear wheels 8, thereby permitting the transmission of rota motion to the saine. lounted on the shalt 13 are beveled gears 27, which arranged to mesh with other beveled gears 28 carried upon the upper ends of rotatable and internally screw threaded sleeve-like boxings 29.
The Vhousings or casings lare provided with slots fr to slidablyrreceive the shaft 13.
i'adjustably secured between the forward uprights 3 is a transversely disposed bar 32 having a series or" spaced vertically disposed fingers 33 aranged thereon, which in' ai j.. L N lingers as `ull be noten, ai anapted to pass Vbetween the curved hng'ers 11 carried on the apron or conveyor 10, thereby serving as means for thoroughly removing all matter from the endless conveyor before the same is rengaged with the pile or stack of matter.
.A sprocket wheel 34 is mounted upon one `endV oit the forward axle of the 'frame and is adaptedl to be connected with a similar wheel 35 carrying a gear 35 movably mounted 0n a stub axle 36 supported in suitable bearings arranged in the adjacent uprights 3 and meshing with the adjacent gear wheel 14.
To permit the transmission ot power to the endless apron 10, the shaft carrying the pulley 7 is extended and carries a pulley 38, about which a belt or other suitable torni et gearing is` arranged, this belt, of course, y
being extended into engagement with the driving means or source ot power.
rllhe operation ot the device may be reviewed as follows:
The rear end oi the apron 1() is in its uppermost position with respect to the rear at the front ene of the device, 'from where' it will be discharged into a receptacle or body of a vehicle adapted to be positioned over the tongue 5 and beneath the forward projecting portion of the apron. During movement oit the apron 1G, rotary motion will be imparted from the gear wheels 3 to the gear wheel 26 and from there rotary motion will be imparted to the screw threaded Y boXings 29 which boxings, due to the weight of the material will leave the upper rotatable sleeves 2O and engage with the screw threaded shafts 17 and a consequence, move downwardly causing' the r ar end ot the apron to be gradually lowered with respect to the pile or stach ot matter being loaded or handled thereby and against the side ot which the supporting trame 1 is backed. lWhen the rear end of the apron is its lowermost position, the bearings 29 will have engaged with the short screw threaded sleeves 22 and the weight of the apron will be such to cause the movement of said sleeves to their lowermost positions against the resistance of the springs 23,
thorn-by placing the expansible coil springs 23 under tension and Adisengaging the recesses 211 and spurs 25. rlhus, the continued rotation oit the boXings will not atleet the apron, since, as before stated, the sleeves'r22 are loosely mounted on the smooth lower portions 18 of said shafts and rotatec around the shafts. `When all matter has been removed from the apron, the weight of the same is of course lessened and the eX- pansible coil spring 23 then expands and causes the recesses 24 and 25 to be reengaged. The drive through the pulleys 38 is then reversed and as a consequence, the boxings 28 will be caused to ascend the screw threaded portions of the shafts 17 until the same move into engagement with the upper short sleeves 20. Since these upper short sleeves 20 are also loosely mounted o n the upper ends of the shafts 17, continued rotary movement of the boXings will not affect the positioning of the apron 10 after the same has been moved to its uppermost position with respect to the uprights l. At this time, it becomes necessary to move the device backwardly so that the apron 10 may be again engaged with the side of the pile or stack of matter. To accomplish this, the sprocket wheels are moved into engagement with the wheels 14 and due to the reversed drive of the apron,'the device will of course be moved backwardly to the desired position with relation to the pile or stack of matter, whereupon the wheels 14: and 85 may be disengaged to prevent the transmission of motion to the wheels 2. Furthermore, the sprocket wheels 14 may be moved to their outermost positions upon their respective shafts 13 and maintained in such positions by position of the pin 15. flhus, upon operating the apron 10, the transmission of rotary motion to the wheels 14 and hence to the wheels 35 will be prevented. Then the rear end of the apron 10 has been raised and properly positioned with respect to the stack, the drive may be then. stopped and changed to forward Thus, when again started the apron 10 will lmove in the direction indicated by the arrow and will again remove a portion of the stack or pile of matter and eifectually load the same into the body of a waiting vehicle. All matter will be thoroughly dislodged from the curved fingers 11 by provision of the cleaner element comprising the bar 82 and spaced pins 33, which pins as will be understood, engage between the curved fingers 11.
While 1 have illustrated and described, with a considerable degree of particularity, constructional details of the device embodying my invention, it is to be understood that the invention is not limited to the particular form and arrangement of the several parts which may be modified within a wide range without departing from the essence of the invention, the construction shown and the description based thereon being intended to be taken in an illustrative rather than a limiting sense.
